Abstract
Description
Technical Field
[0001] This utility model relates to the field of polymer material processing technology, and in particular to a raw material proportioning machine for environmentally friendly TPE thermoplastic elastomers. Background Technology
[0002] TPE (thermoplastic elastomer) is a polymer material that combines the properties of plastics and rubber. It possesses the elasticity of rubber and the processability of plastics. TPE softens at high temperatures and solidifies upon cooling, making it ideal for injection molding and extrusion. It boasts advantages such as weather resistance, abrasion resistance, and chemical resistance, and is widely used in automotive, electronics, home furnishings, and medical fields. In the production of TPE, the precise proportioning of raw materials is crucial, as its final performance is directly related to the ratio of raw materials. To ensure the accurate and uniform proportions of each raw material in TPE production, a raw material mixing machine becomes a key piece of equipment. The raw material mixing machine achieves precise weighing, mixing, and conveying of different components, thereby effectively guaranteeing the production quality of TPE.
[0003] The TPE thermoplastic elastomer raw material proportioning machine mainly consists of a feeding system, a weighing system, a mixing system, and a control system. The feeding system is responsible for conveying various powder, granular, and liquid raw materials from different raw material warehouses to the equipment. The weighing system is used to accurately weigh the mass of each raw material, ensuring they are mixed in a predetermined ratio. The mixing system uniformly mixes the various raw materials, resulting in a final TPE product with consistent physical properties.
[0004] The aforementioned TPE thermoplastic elastomer raw material proportioning machines still have some shortcomings in terms of environmental protection. Traditional proportioning machines often fail to effectively recycle and utilize waste and powder generated during the production process. These wastes often contain underutilized raw material components, and their waste will have a significant impact on the environment. The lack of an environmentally friendly powder recycling system makes waste disposal a difficult problem, increasing production costs and failing to meet the environmental requirements of sustainable development. Therefore, an environmentally friendly TPE thermoplastic elastomer raw material proportioning machine is proposed to solve the above problems. Utility Model Content

The vacuum cleaner 10's recovery system operates continuously during the mixing process, removing powder from the mixing cylinder 2 to ensure high quality and low pollution of the mixture. The temperature control system for the mixing process regulates the temperature of the mixing cylinder 2 through a temperature controller 13 and a temperature control layer 14, ensuring that the mixture is stirred under suitable temperature conditions, thereby avoiding the impact of improper temperature on the quality of the raw materials and the mixing effect.

A cleaning ring 19 is externally connected to the cleaning push rod 18, on which multiple flexible brushes 20 are evenly distributed. These brushes, under the action of the cleaning push rod 18, can move and effectively clean material residues and dirt inside the mixing housing 1. The cleaning cylinder 17 uses airflow to propel the extension and retraction of the cleaning push rod 18, ensuring that every cleaning corner is thoroughly cleaned. The efficient operation of the cleaning system guarantees the long-term stable operation of the equipment and avoids cross-contamination between different raw materials.
